why do countries such as South Korea and China have latin numbers and letters on their license plates when their language doesn’t use them?

Question

Edit: Latin letters and numbers might not be the right word. I meant letters such as AaBbCc and numbers such as 123.

In: 3829

Answer 1

South Korea license plates do not use latin letters. They use one syllable (in Korean) followed by numbers. Also, I have no idea where you got the idea that they don’t use the same numbers.
